White Flowers Attract Pollinators Also

Phlox happens to excel at white.

Floral color attracts pollinators. Hummingbirds mostly prefer bright red, pink and orange. Butterflies mostly prefer bright orange and yellow. Bees prefer bright blue and purple, but are less discriminating than other pollinators. Of course, these are mere generalizations. Otherwise, the majority of pollinators might ignore species that bloom with white flowers.

Realistically, most flowers do not rely on pollinators for pollination. They rely exclusively on wind, so are just green or brown, and not visually prominent. These include flowers of grasses and conifers. Otherwise, small but prominently prolific white flowers are the next best option. They rely on either or both wind and pollinators for very effective pollination.

For example, firethorn bloom is very appealing to bees and other pollinators. It is also so prolific that some of its pollen disperses into the wind. Its tiny but abundant white flowers can not avoid pollination by one means or the other. Most orchard trees, such as apricot, plum, apple and pear, use the same technique. So do viburnum, photinia and elderberry.

This should not imply that white is a substandard color, though. After all, white flowers do attract pollinators. Several pollinators, such as nocturnal moths, prefer luminescent white flowers. More importantly, many pollinators see more than white. Several types of Insects see ultraviolet. What seems to be white to us can actually be elaborately colorful to them.

Furthermore, white needs no justification. It happens to be the best color option for some garden applications. It brightens visually dark situations, and mingles well with almost all other colors. A few types of flowers, particularly those with distinctive form, excel at white. Calla, camellia, lily of the valley and various lilies are only a few of numerous examples.

Cool season annuals for autumn and winter will soon replace old warm season annuals. White busy Lizzie, petunia, cosmos, alyssum, snapdragon and zinnia are finishing soon. White pansy, viola, dianthus and wax begonia may replace them. Later in autumn, white cyclamen will become seasonal. There are always enough white flowers to choose from.

Six on Saturday: Major, Minor & Unidentified

Two of my six for this week were purchased, which is rare in my garden. Two were gifts. Two were acquired by other questionable means.

1. Sorbus americana, American mountain ash does not conform to my theme. It is about average and identifiable. I merely wanted to show it off because it is the only seedling to grow from several seed. It can be reasonably productive without another pollinator tree.

2. Cerinthe major, honeywort grew from seed from Tangly Cottage Gardening. This is its first bloom here. Because I did not sow all the seed this year, I could sow more next year. If it self sows here, it will likely only do so within gardens which are generously irrigated.

3. Vinca minor ‘Alba Variegata’, small white variegated periwinkle was another gift from Tangly Cottage Gardening. Although white is my favorite color, these little white flowers do not look very impressive against the background of their yellowish variegated foliage.

4. Pelargonium graveolens, scented geranium, like two other scented geraniums here, is unidentified. I think that the other two are lemon and rose scented geraniums. This one has a less distinct or identifiable foliar aroma, but has prettier and more colorful bloom.

5. Dahlia is also unidentified. I know what it is not, though. It is most definitely not any type of assorted dinnerplate dahlia, which I purchased it as. Although pretty, its flowers are only about three inches wide. Foliage stands about as tall as that of a bedding dahlia.

6. Canna is the third unidentified subject of these six; but it is one of the most important of the many Canna here. It is a souvenir from the funeral of an old friend two years ago. It did not bloom last year, so this is the first time that I confirmed that it blooms yellow.

Late Summer Flowers Bloom Now

Pot marigold is an autumn annual.

Spring is the season with the most flowers. Winter is generally the season with the least. That is, of course, a generalization. There are plenty of flowers that bloom exclusively for winter color. Plenty more bloom randomly throughout the year, regardless of season. For now, late summer flowers are the most prominently colorful. Autumn flowers will be next.

Realistically, no bloom is random. Even flowers that bloom randomly throughout the year do so only because they can. Such flowers are mostly from mild climates where they can disperse seed at any time. Any pollinators that they rely on are also active throughout the year. Many randomly blooming flowers can effectively conform to more distinct seasons.

Most flowers bloom within a distinct season because it is most convenient for them. Most bloom for spring to maximize the time for their seed to develop before winter. Many of the earliest are tiny but abundant because they rely on wind for pollination. Later flowers can be bigger and more colorful to attract pollinators. Late summer flowers are no exception.

Different flowers have different priorities. Some of the earliest spring bloom needs time to produce seed after bloom. Several late summer flowers conversely need time to develop their blooms. Then, they produce seed relatively quickly before winter. This is why some late summer flowers are bolder but less abundant than spring flowers. They require time.

For example, sunflowers with relatively small blooms may bloom as early as late spring. However, those with bigger and bolder blooms are more familiar as late summer flowers. Such big blooms do not grow quickly, but are ready for their late pollinators nonetheless. They compensate for their lack of abundance with spectacularly grand individual bloom.

Many late summer flowers happen to be related to sunflowers. They include coneflower, dahlia, zinnia, sneezeweed, aster, and cosmos. Dahlias with larger flowers are later than those with smaller flowers. Marigold and chrysanthemum will become more seasonable later and into autumn. Unrelated canna and various sages are blooming well about now.

Six on Saturday: 4:00

Four o’clock has been unusually pretty in bloom. It self sows almost enough to become a weed, but I am fond of it.

1. Mirabilis jalapa, four o’clock blooms in various shades of pink, including one that can be fragrant about 4:00 and into evening. It alternatively can bloom white, red, magenta, yellow, or with striped combinations of colors. Different colors may bloom on one plant.

2. Mirabilis jalapa, four o’clock does not exhibit very much variation of floral color here, though. This yellow bloom is one of only three variations. I thought that I noticed simple red bloom through previous summers, but can find none now. I would like to find white.

3. Mirabilis jalapa, four o’clock demonstrates what can occur when the two other colors here combine. It is the third of only three variations that I am aware of. From a distance, it seems to be peachy orange. Some of its flowers are just like the first two pictures here.

4. Nerium oleander, oleander that blooms pink mingles with the oleander which blooms white that I posted a picture of three weeks ago. Oleander is so cheap and common here that, even with oleander scorch, it is still the primary shrubbery for freeway landscapes.

5. Fuchsia magellanica, fuchsia is easy to miss where it is wedged between healthier and prettier hydrangea and canna. I should grow copies of it elsewhere. It would probably be bigger with fuller foliage where it gets more water than the four o’clock and oleander get.

6. Rosa spp., rose is in a rose garden that is nowhere near the four o’clock, oleander and fuchsia, but is too pretty to omit. I believe that it is ‘Double Delight’. It is nicely fragrant. Flowers bloom white with red edges, but fade to mostly pinkish red, just as they should.

 Passion Vine

Passion vine has the weirdest flowers.

My niece knows the weird flowers of passion vine as ‘flying saucers’ because they look like something from another planet. The most common species, Passiflora X alatocaerulea, has fragrant, four inch wide flowers with slightly pinkish or lavender shaded white outer petals (and sepals) around deep blue or purple halos that surround the alien looking central flower parts. The three inch long leaves have three blunt lobes, and can sometimes be rather yellowish. The rampant vines can climb more than twenty feet, and become shabby and invasive, but may die to the ground when winter gets cold. Other specie have different flower colors. Some produce interesting fruit. Passiflora edule is actually grown more for its small but richly sweet fruit than for flowers.
